CarieScan PRO

With an accuracy level of 94.8% in detecting caries and healthy tooth structure, the CarieScan PRO is quite simply the most accurate caries detection device ever produced! That means greater confidence for you and piece-of-mind for your patients. The CarieScan PRO reduces the need for potentially harmful X-rays, which saves both time and costs.

The CarieScan PRO provides repeatable data to monitor caries over time, enabling timely preventative treatment and supports evidence-based care plans.

The PRO uses a measurement method called the AC Impedance Spectroscopy technique. This method relies on the application of a small alternating electrical signal (undetectable by the patient) through the tooth while monitoring the response at the sensor. By changing frequency of the applied signal, a spectrum is captured which provides valuable insights into the physical and chemical properties of the tooth.

The impedance of a healthy tooth is very high due to relatively low ionic conduction. However, as a tooth demineralises it starts to lose some of its regular structure from beneath the tooth’s surface and increasingly larger pores are formed as minerals are eluted out. If the lesion progresses, the pores can connect with each other and the tooth becomes a mix of highly conductive parts (the fluid filled pores) and the low conductive enamel, so impedance decreases. As the decay progresses, dentine becomes involved and cavities are formed, the impedance falls further.

The variance in signals between the different stages of decay is significant. The impedance measured in a healthy tooth is significantly greater than that of a tooth that is demineralising which is itself significantly greater than that of a tooth with a cavity. As a result the sensitivity (ability to find caries when it is present) and specificity (ability to detect healthy tissue, or lack of false positives) of the CarieScan PRO in distinguishing these different stages is very high.

The CarieScan PRO has a number of advantages over other methods, and the accuracy of results sets CarieScan PRO apart from other diagnostic methods.

Two basic questions dentists need to answer when using any caries detection technique (be it clinical visual, radiography or a new technology) are:

• ‘How accurate is the detection technique at differentiating between caries lesions and sound sites in the context in which I am working?’
• ‘How can it help me to decide between three management options in relation to a detected lesion: monitor, apply preventive therapy, or treat operatively?’

The performance index, or functional accuracy, shown below enables clinical decision-making with regard to: (a) correctly detecting the absence of clinically apparent early stage disease (threshold of intervention for preventive therapeutic options) and (b) correctly detecting the presence of disease at a potentially operative intervention stage.
